Application filed August 2, 1915. Serial No. 43,255.

"0 all whom it may concern:

Be it known that we, JOHN L. PATTERSON and LOUIS S. CANNON, citizens of the United States, residing, respectively, at Roanoke Rapids and at Rosemary, both in the county of Halifax and State of North Carolina, have invented certain new and useful Improvements in J acquards, of which the following is a specification.

This invention relates to jacquards for use with looms, and particularly to a modification of a portion of the jacquard mechanism to render it positive in its action and thus better suited to the control of pattern reverse mechanisms, card repeaters, stop motions, counters, box-irotions and the like.

The invention is applied to existing jacquards by substituting a special needle and a corresponding special upright for a regular needle and upright, and adding an auxiliary blade to the grifi' frame. The special upright has its hook reversed so that it engages the auxiliary griff blade when the special needle is forced back. The special needle has an enlarged head lying in a countersunk hole in the needle board and is forced back by projecting clips mounted on the ends of appropriate cards. These clips are engaged by th card cylinder when the card is presented, and are forced into the countersunk hole. The reversal of the hook of the upright gives it a normal freedom from the gritf blade making accidental actuation impossible, while the size and arrangement of the parts is readily made such as to secure a far more certain action than can be had with the usual card and needle. An additional advantage is the ready identification of the control cards by the presence upon them of the clips. This permits quick inspection in case of faulty action and is a convenience to the weaver.

One or more of the special needles and uprights may be used according to the requirements of the jacquard control mechanism, the special upright or uprights being connected in any approved manner to the reverser, card repeater or the like to actuate the latter.

The invention is generally applicable in lieu of the conventional jacquard needle and upright in the various mechanisms in which these are used to control the travel of the pattern series, etc. It may thus serve to actuate the pattern reverse in simple reverspatterns in a single series (see patent to Patten No. 578,068); the card repeater in auxiliary cylinder jacquards (see patent to Deering N 0. 953,379) and various other repeating and reversing mechanisms. It may also be used with conventional forms of stop motion to bring the loom to rest at stated points inthe pattern. This is useful where the filling is tocbe changed as in weaving color stripes in borders. It may also be used to actuate counters to indicate the number of complete patterns woven, and also to operate boxes on looms.

We show the invention as applied to an auxiliary cylinderjacquard to control the operation of the cylinders, in the accompanying drawings, in which:

Figure 1 is a side elevation of a jacquard, various parts not necessary to an'understanding of the invention being omitted;

Fig. 2 is a diagrammatic vertical section indicating the relation of the needles, hooks and the griff bar and showing the relation of the needles to the two pattern cylinders;-

Fig. 3 is a detail elevation of a form of card repeater or control mechanism. known in the art and available for use with the invention;

Fig. 4 is a perspective view of one end of a card showing the clip attached;

Fig. 5 is a fragmentary horizontal section through the needle board showing the special needle mounted in a countersunk recess and also showing the relation of this needle to the card and the clip carried thereby;

Fig. 6 is a fragmentary perspective view of a portion of one of the regular griff bars showing the special grifi' bar attached there to and the relation of these parts to the special and regular uprights.

In the drawings 7 represents the frame of the acquard, 8 is the main cylinder and 9 is the auxiliary cylinder. The main cylinder coacts in the usual way with the needle board 10, having a bank of needles 11, which control the usual series of uprights 12, the parts being so arranged that when a needle is indicated by a hole in a pattern card the corre sponding upright will be hooked to its grif'f bar; but when the needle is forced back by the card, the upright will be carried clear of the grill bar. The same uprights are also operated by means of a bank of auxiliary needles 13 which pass through an auxiliary needle board 14, and with which the auxiliary cylinder 9 coacts. The auxiliary needles are connected to corresponding main needles by means of rock levers l5, pivoted in the usual way as diagrammatically illustrated at 16. Thus the effect of any pattern series on the uprights'would be the same whether presented by the main or the auxiliary cylinder. In the ordinary use of such a jacquard one cylinder carries the cross border pattern and the other carries the body pattern, either as a complete pattern, or as a repeating section.

The cylinders 8 and 9 areguided in their irotions toward and from their respective needle boards by the guide rods 17 and 18 which may be alternately latched to a rocker arm 19 driven in any suitable manner. The method 'of connection is through two slide bars 20 and 21 which run on'the inner ends of the guides 17 and 18. These carry gravity pawls '22 and 23 which when lowered engage studs 24 and 25 on the slide bars 17 and 18 respectively. Only one of the pawls 22 and 23 is permitted to be in engagement at once, one or the other being held up by an S- shaped rocker arm 26 pivoted at 27 on the frame 7.

This rocker arm .26 is actuated through a link 28 from a lever 29 whose position is controlled by a pattern chain 30. This chain 30 runs on a sprocket 32 which is periodically fed forward one tooth at a time as will be described. Certain of the links have enlargements or bosses 31. When an enlargement or boss 31 is under the lever 29 it raises this lever and shifts the arm 26 to disengage the pawl 23 and permit the pawl 22 to engage. When a link having no enlargement .31 is beneath the lever 29 this drops and the arm 26 shifts to change the action of the pawls. Thus the pattern chain determines which of the cylinders 8 and 9 is in operation to control the uprights 12. A pawl 33 is actuated each pick by the movement of the lever 19 to which it is connected. The pawl is normally held up by a spring-held lever 34 which engages a lug 35 on the pawl 33. When the lever 34 is drawn down against its spring the pawl 33 may engage a ratchet 36 to feed it forward one tooth, thus advancing the pattern chain one link.

The mechanism so far described has been used for controlling auxiliary cylinder jacquards, the operation of the lever 34 being effected by connecting it to an upright in.

the jacquard which is operated through the indication of its corresponding needle by a corresponding hole presented in the termi nal card of the series. False indication and failure to indicate are common occurrences in such, devices, and cause serious losses of time and material. To avoid the uncertainty of jacquard indication we have devised a new mechanism for controlling the above described device and other snnllar de vices, our improved mechanism'being readily applicable to existing jacquards.

The lever 34 is connected by means of cords 37 and a bell crank 38 to an upright 39. This upright is similar to the usual up: rights used in the jacquard except that its hook at the upper end is turned in the reverse direction and maybe engaged and lifted by an auxiliary grill" blade 40 mounted on one of the usual grifl" blades 41. The re versal of the hook on the upright 39 causes this upright always to remain in its lower position unless positively shifted to hook upon the auxiliary blade 40. The special upright 39 is connected in the usual manner which. is commonly made of metal and riveted to the end of the proper pattern card 45, as best shown in Figs. 4 and 5-. Whenever a card carrying the clip 44 is presented in either pattern series the special upright 39 is shifted to engage the special. grifibla'de' 40 and consequently the lever 34 is momentarily drawn down through the connections I, 37 and 38 thus causing the pattern chain 30 to be fed forward one link and perform its usual function in controlling the alternate action of the two pattern series 8 and '9.

The fact that the special needle is 001111 tersunk precludes any accidental actuation due to misplaced or ovcr-running cards in the series and the relatively large size of the parts insures peculiarly certain v operation whenever a clip card is presented. The presence of the clips on the cards allows the weaver to see how the pattern is progress ing even at some distance from the loom, and in case of defective operation permits ready identification of the control cards.

Th invention is readily applied to existing looms by simply changing the needles, reversing the hook on the upright, and adding the special griff blade. It is not com fined in its utility to auxiliary cylinder jac-' quards but as already suggested is generally applicable wherever card repeaters and anal-..

ogous devices are used in this art. I In some cases more than one special needle might be used in a single bank of needles, for example in looms where a pattern is caused to reverse. at its opposite ends, and the difi'erent reverse mechanisms are individually actu ated. A single bank might also be provided with more than one special needle, one for example controlling a card repeater and another a stop mechanism to mark the point where the filling is to be changed in color. Various such uses will sug est themselves to those skilled in the art, and fall Within the scope of our invention.

Various changes are possible in the construction of the cards, needles and similar parts. One of the important advantages of the device arises from the fact that the special needle is beyond the range of action of ordinary cards, the special cards being provided with extensions to permit them to coact with the special needle. The use of a countersunk needle and a projecting lug affords the most convenient means of availing of this principle, because it does not require a special location for the needle other than the countersinking of its end. Other locations of the special needle are, however, possible for use with cards having suitable extensions or projections to coact therewith. The special gritl blade and hook are also subiect to possible modifications of form.
